T1172: Additional Tax on Accumulated Income Payments from RESPs

If you have a Registered Education Savings Plan (RESP), a part of the income earned from it is called your accumulated income payments (AIP). Any AIP amounts you received in 1999 or later need to be included in your annual income and are subject to an additional tax of 20% (12% for residents of Québec) which is calculated on the T1172: Additional tax on accumulated income payments from RESPs page of your return.

Note: If you’re a resident of Québec, you’ll need to complete the TP-1129.64-V: Special tax relating to a registered education savings plan.

You can find your AIP amount in box 40 of the Other information section on your paper T4A slip.
